on the entire police investigation comes up cited in favor of the suspect brgy tanod only that it was suicide though there were no crime scene technician or SOCO processed the crime scene and the deceased that should support.

Question: if murder was committed by the brgy. tanod and there is willful intent to cover up committed by the policemen in attending to the alleged suicide incident, is cover up conspiracy or accessory to the crime?

accessory by concealing or destroying the body of the crime, or the effects or instruments thereof, in order to prevent its discovery.

with regards to this case i posted, a resolution has already came out with homicide against the brgy. tanod stating there we're no direct witness;

question: 1) is there anything we can do to amend it from homicide to murder? how?
2) is there a murder case prosper without direct witness?
3) whose case?

thank you for the reply.

i understand why you would want the crime to be non-bailable. but you have to provide direct proof of qualifying circumstances. if none were appreciated by the investigating fiscal, then you cannot force him.

if you try to file an MR, the effect is that it will delay the case.
